What do you mean remapped?

If you mean retuned, then the new Convertor and Flywheel must have thrown the adaptive learning off. timing and Ignition is off now, you are not burning all the fuel that is being Squirted in the Motor. Have the tuner return it to OEM and then retune it. bc to me it sounds like that is the Problem. Did you put the same donut back in and the same oem flywheel? or did you go with a stage kit? Bc these beemers are very sensitive. Have that checked out. Let me know waht it was.

Won't start, starter will spin but will not engage fly wheel to crank up engine


Sounds like the starter drive is shot, best thing to do is replace starter with new or rebuild.
